Abstract

Die vorliegende Erfindung beschreibt ein Verfahren zur Herstellung von Glyoxylsäure durch elektrochemische Reduktion von Oxalsäure in wäßriger Lösung in geteilten oder ungeteilten Elektrolysezellen, dadurch gekennzeichnet, daß die Kathode zu 50 bis 99,999 Gew.-% aus Blei besteht und die wäßrige Elektrolyselösung in den ungeteilten Zellen oder im Kathodenraum der geteilten Zellen noch mindestens ein Salz von Metallen mit einer Wasserstoffüberspannung von mindestens 0,25 V, bezogen auf eine Stromdichte von 2500 A/m², und eine Mineralsäure oder organische Säure enthält.
Das erfindungsgemäße Verfahren hat den Vorteil, daß auf eine hochreine, teure Bleikathode verzichtet werden kann und technisch verfügbare bleihaltige Materialien verwendet werden können, beispielsweise Legierungen, die neben Blei mindestens eines der Metalle V, Sb, Ca, Sn, Ag, Ni, As, Cd und Cu enthalten. Auf ein periodisches Spülen mit Salpetersäure kann verzichtet werden.
